Sheila received x marks in two of her tests and y marks in three other tests.

Her average score in all the five tests in terms of x and y

EVALUATION

Here it is given that Sheila received x marks in two of her tests and y marks in three other tests.

Total marks obtained in first two tests = 2x

Total marks obtained in three other tests = 3y

Number of tests = 2 + 3 = 5

Total marks obtained in 5 tests

= 2x + 3y

Hence the required average score in all the five tests

$\sf = \dfrac{2x + 3y}{5}$
